AIRLINES CANCEL MORE FLIGHTS

Update: More than 8,300 flights have been canceled this weekend from North Carolina to Boston, more than 3,600 of them on Saturday alone, according to the Associated Press.

Southwest Airlines has canceled 400 flights along the eastern seaboard through Monday, while its subsidiary AirTran Airways has canceled about 300 flights during the same time period. Delta is canceling about 600 flights on Saturday and 1,500 flights between Saturday and Monday. They join JetBlue, which canceled 880 flights due to the storm.

AREA AIRPORTS REMAIN OPEN, FLIGHTS CANCELED

The three area airports remain open and have no plans to close today, though Washington and Baltimore aren’t exempt from the widespread cancellations.

Every flight scheduled to arrive at or depart from Baltimore Washington International Airport tonight has been canceled. (The airport’s Web site shows lists only one flight as on-time: a Southwest Airlines flight departing at 4 a.m. for Phoenix. Time will tell.)

“Airlines have canceled most of their service this afternoon at BWI,” airport spokesman Jonathan Dean said earlier today. There were no plans to close the airport unless there was an unexpected change in the weather. He said airlines indicated that they planned to resume normal operations Sunday afternoon, but that’s all dependent on the weather.

Dulles and Reagan National both remain open, with no plans to close either airport, said Courtney Mickalonis, a spokeswoman for the Metropolitan Washington Airports Authority. Obviously, that’s also dependent on the weather. They weren’t expecting a lot of passengers to be stranded overnight at either airport, because there was a lot of warning and people had time to make other arrangements, she said.

Head here for a full list of airlines serving Reagan National, Dulles International and Baltimore-Washington International airports, so you can contact your airline for flight and rebooking information. The information listed on airport and airline Web sites is helpful but not always up to date; it’s best to contact your airline directly to make sure.

NEW YORK SHUTS DOWN AIRPORTS

UPDATE: Teterboro Airport is open right now and will remain open until 10 p.m. tonight, according to the Port Authority.

The Port Authority will close the five main airports in the New York area to arriving flights beginning at noon today. That means John F. Kennedy International, Newark Liberty International, Stewart International, LaGuardia and Teterboro airports will all be closed to arriving planes, which will in turn have a severe impact on a lot of other flights in a lot of areas. Head here for a list of airlines serving the three Washington area airports so you can contact your airline to see about your flights and rebooking.

TUNNELS IN NORFOLK AND HAMPTON ROADS

The Virginia Department of Transportation closed the Midtown Tunnel at 10 a.m. and closed the I-64 Hampton Roads Bridge-Tunnel at 11 a.m. Drivers are warned to stay off the roads until the storm passes.
